(I] Tips
For s afety reasons, t he pa rking br ake is r eleased automatically only
when the driver 's safety belt is engaged in the buck le .•
Starting off with a trailer
To prevent rolling back unintenti onally on an incline, do
the following :
-Keep the switch pu lled and depress the accelerator. T he
parking brake stays a pp lied and prevents the vehic le from
ro lling backward.
- You can re lease the switch once you are sure tha t you are
deve lopi ng enough driving force at t he wheels by
depressing the accelerator .
Depending on the we ight of the rig (vehicle and trailer) and the
sever ity o f the in cl ine, you may roll backwa rds as you start . You can
prevent roll ing backwards by holding the park ing brake sw itch pulled
out and accele ra ting -just as you wou ld when starting on a hill wi th a
conventional hand brake .•
Emergency braking
In the event that the conventional brake system fails or
locks .
-In an emergen cy , pull t he sw itch and contin ue to pull it to
slow your vehic le down with t he p arking brake.
- As soon as you re lease t he swi tch or acce lerate, the
bra king process s tops.
If you pull the switch and hold it above a speed of about 5 mph (8
km/h), the emergency braking fu nction is initiated . The vehicle is braked at all four wheels by activating the
hydraulic brake system.
Th e b rake pe rformance is s imila r to mak ing an eme rge ncy sto p .=>
&
In order not to act ivate the emergency brak ing by m istake, an audib le
warning tone (buzzer) sounds when the switch is pulled. As soon as
t he swi tch is re leased, or the acce lerator pedal is dep ressed , emer ­
gency braking stops .
& WARNING
Emergency braking should only be used in an eme rgency , when
the normal foot brake has failed or the brake pedal is obstructed .
Using the parking brake to perform emergency braking will slow
your vehicle down as if you had made a full brake application . The
laws of physics cannot be suspended e ven with ESP and its associ ·
at ed components (ABS, ASR, EDS ). In corners and when road or
weather conditions are bad , a full brake application can cause the
vehicle to skid or the rear end to break away· ri sking an accid ent. •
Driver messages in the instrument cluster
Warning Vehicle incline i s excessive
Th is message appears when the parking brake is applied on an incline
t ha t exceeds abo ut 3 0%.
I n th is case the braking power of the parking brake may
not be
adequate
to prevent the vehicle from rolling unintentionally.
Pl ease release parking brak e
Please note that for safety reasons the pa rking brake is re leased auto ­
matically on ly if the d river's seat be lt is fully engaged i n the buck le .
To relea se the parking brake pre ss the brake pedal
Th is dr iver message appears when the switch to release the parking
brake was pressed . The par king brake can only be released if you s tep
on the brake peda l and at the same time p ress the switc h or you auto- _.,

Trailer towing
Driving with a trailer
General information
Your Audi was designed primarily for passenger transpor ­
tation.
If yo u plan to tow a t rai ler, p lease rem emb er that the add itiona l load
wi ll affect durab ility, economy and performance.
T railer tow ing not on ly p laces mo re s tress on the vehicle, it a lso calls
for more concentrat ion from the driver.
For this reason, a lways follow the ope rating and dr iv ing instr uctions
prov ided and use common sense .
Technical requirements
Trailer hitch
Use a weight-carrying hitch conforming to the gross trailer weig ht.
Th e hitch mus t be suitable for yo ur vehicle a nd tra ile r and mus t be
mounted secure ly on the vehicle's chassis at a
technically sound l oca­
t ion. Use only a trailer hitch wi th a remov ab le b all m ount. Alw ays
check w ith the tra iler hitch manufacturer to make sure that you are
using t he cor re ct hi tch.
Do not use a bumper hitch.
The h itch must be installed in such a way t hat it does not interfere
w ith the impa ct-absorbing b umper system. No mod ifi cat ions sho uld
be made to the vehicle exhaust and brake systems. From time to
ti me, chec k tha t all hitc h mou ntin g bol ts rem ain secure ly f aste n ed.
When you a re not tow ing a tra iler, remove the tra iler hitch ba ll
mount. This prevents the hitc h from caus ing damage should yo ur
vehicle be struck from behind=> &.
Controls and equip­
ment Safety first Vehicle operation
Trailer brakes
If your trailer is eq
uipped with a braking system, check to be s ure that
i t confo rm s to all regula tions.
The tra iler hydraulic brake system must not be directly connected to
the vehicle's hydraulic brake system=>& .
Safety chains
Alw ays use safety chains be twee n your vehicle and the trai ler.
Trailer lights
Tr ailer l ights m ust meet all reg ulat io ns. Be su re to check with your
author ized Audi deale r for correct wir ing, switches, and re lays.
Mirrors
If you are unab le to see the traffic behind you us ing the regular
outside m irro rs, then you
must install extended m irro rs. It is impor­
tant that yo u
always have clear vision to the rear.
& WARNING
• If a trailer has electrical b rake s please note that these brakes
are not activated by the factory-fitted control unit -ri sk of acci­
dent!
• After removing the trailer hitch , do not store it in your vehicle.
In case of sudden braking, the hitch could fly fo rward and injure
you or your passengers. •
Operating instructions
Maximum trailer we ight
A trailer for your vehicle is limited to a typical class 1 or class 2 trailer . .,.
Vehicle care Do-it-yourself service Technical data

Trailer towing
"-------------------------------------------------
Trailer load distribution
Be sure the load in the trailer is held securely in pla ce to prevent it
from shifting forward, backward or s ideways.
Never allow a passenger to ride in a trailer => & in "Driving instruc­
tions" on
page 256.
Engine cooling system
Towing a trailer makes the eng ine work harde r. It is important that
the cooling system's performance is up to the additional load. Make
sure that the cooling system has enough fluid.
Tire pressure
When towing a trailer, inflate the tires of your vehicle to the cold tire
pressure listed under "Full load" on the label located either on the
dr iver's side B-pillar (visible when the door is open) or inside the fuel
filler flap . Inflate trailer tires to trailer and tire manufacturers' spec­
ifications.
Lights
The headl ight settings should be checked w ith the trailer attached
before driving off. Check to make sure both vehicle and trai ler lights
are working properly.
Safety chains
Be sure trailer safety cha ins are properly connected from the trailer
to the hitch on the vehicle. Leave enough s lack in the chains to permit
turning corners. When you install safety chains, make sure they will
not drag on the road when you are driving.
T he chains should cross under the trailer tongue to p revent it from
dropping in case of separation from the hitch.
Driving instruct!ons
Driving with a trailer always requires extra care and
consideration.
To obtain the best possible handling of vehicle and trailer,
please note the following:
- Do not tow a loaded trailer when your car itself is not
loaded.
- Be especially careful when passing other veh icles .
- Observe speed limits.
- Do not drive at the maximum permissible speed.
- Always apply brakes early.
- Monitor the temperature gauge .
Weight distribution
Towing a loaded trailer w ith an empty car results in a highly unstable
distr ibution of weight. If this cannot be avoided, drive at very low
speeds only to avo id the r isk of losing steer ing control.
A "balanced" rig is easier to operate and control. Th is means that the
tow vehicle should be loaded to the extent possible and permissible,
wh ile keeping the trailer as light as possible under the c ircumstances.
Whenever possible, trans fer some cargo to the luggage compart ­
ment of the tow vehicle while observing tongue load requirements
and vehicle loading considerations.
Speed
Th e higher the speed, the more difficult it becomes for the driver to
control the r ig . Do not drive at the maximum permiss ible speed.
Reduce your speed even more if load, weather or wind conditions are
unfavorable -part icularly when go ing downhill.
Reduce vehicle speed
immediately i f the trailer shows the slightest
sign of swaying.
Do not try to stop the swaying by accelerating. _,

Observe speed limits. In some areas, speeds for vehicles towing
t railers are lowe r than for regular veh icles.
Always apply brakes early. When dr iv ing downh ill, sh ift in to a lower
gear to use the engine braking effect to slow the vehicle. Use of the
brakes alone can cause them to overheat and fail.
Coolant temperature
The coolant temperature gauge~ page 8 must be observed care­
fully. If the needle moves close to the upper end of the scale, reduce
speed immediately and/or turn off the air conditione r.
If the coolant temperature warning light in the instrument cluster
star ts flashing
-t- , pull off the road, stop and let the engine idle for
about two minutes to prevent heat bu ild-up.
& WARNING
Anyone not properly restrained in a moving vehicle is at a much
greater risk in an accident. Never let anyone ride in your car who is
not properly wearing the restraints provided by Audi. u
Trailer towing tips
Important to know
------------
Your vehicle handles differently when tow ing a tra iler because of the
additiona l weight and different weight distribution. Safety, perfor ­
mance and economy will greatly depend on how carefu lly you load
your trailer and operate your rig .
Before you actua lly tow your trailer, practice turning, stopping and
backing up in an area away from traffic. Keep pract icing until you have
become completely familiar with the way your vehicle-t railer combi­
nation behaves and responds.
Controls and equip­
ment Safety first Vehicle operation
Backing up
is d iff icult and requ ires practice . Backing up with a trailer
generally requires steering action opposite to that when backing up
your vehicle without a trailer.
Maintain a greater distance between your vehicle and the one in front
of you. You will need more room to stop . To compensate fo r the
trailer, you will need a larger than norma l turning radius.
When passing, remember that you cannot accelerate as fast as you
normally would because of the added load. Make sure you have
enough room to pass. After passing, allow plenty of room for you r
trailer before changing lanes again.
Avoid jerky starts, sharp turns or rapid lane changes .
[I) Tips
• Do not tow a trai ler during the break-in per iod of your vehicle.
• If you tow a tra iler, your Audi may requi re more frequent mainte­
nance due to the extra toad~
page 343. •
Parking on a slope
Do not park on a slope with a trailer. If it cannot be
avoided, do so only after doing the following:
When parking:
-Apply the foot brake.
- Have someone place chocks under both the vehicle and the
trailer wheels.
- With chocks in place, slowly release the brakes until the
wheel chocks absorb the load.
- Turn the wheels towards the curb.
- Apply the parking brake .
- Move the se lector lever to
P.

When rest arting afte r parking:
- Apply the foot brake.
- Start the engine.
- Move the selector lever to
D.
- Release the parking brake and slowly pull out and away
from the wheel chocks .
- Stop and have someone retrieve the wheel chocks.
(I] Tip s
If you move the se lector lever of the automat ic transm ission* to P
before applying the parking brake and before blocking the wheels,
you may have to use mo re force late r to move the lever out of the
